Windows only: Freeware backup software FBackup includes special plugins for most popular applications—so you don't have to worry about which files to backup anymore, it's all handled for you.

FBackup can do all the things standard backup applications can do: automated backups, zip compression, password protection, an easy wizard, and even backing up open files—but the killer feature is support for plugins that tell the backup application exactly which files to backup—an extremely useful feature for easily backing up hard-to-find files like the profile folders for Google Chrome, Pidgin, or even Opera without resorting to manually finding each location from deep within a hidden folder somewhere. Sure, you can always backup the entire contents of your drive to make sure you captured everything, but even with today's hard drive sizes that's still a waste of space.
